 Table B is a direct variation.

Step-by-step explanation:

Table A contains data that fits the expression y = x+3.  This is not a direct variation.  The ratio of x and y is not a constant.  Table B matches the expression y = 3x.  This is a direct variation.  Table C can be expressed as y = x - 3.  This is not a direct variation, for the same reason as Table A.

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

tube or goog would be a great resource to with that question
